[Linux-cluster] fence start-up issue

I sometimes run into an issue when a node in my 2-node cluster is
rebooting and hangs on fenced. It seems it can't communicate with the
other node and after the post_join_delay, it fences the other node. This
happened again today, and when the second node rebooted after the fence,
they were in a split-brain configuration.
I saw in the cluster faq, in the cman section, question 6 that the
cluster communication network should be the same network as the fencing
device. I think this may be my problem but I don't understand why. I'm
using HP iLo for fencing and I setup cross-connect cables for the
cluster communication between the 2 nodes. Why would having cluster
communication and fencing on different networks be an issue?
Thanks for your time
